Maple vs. Sweetgum: Identifying by Leaf and Seed

A 2-inch leaf with 7 points is more characteristic of sweetgum (Liquidambar styraciflua) than maple. Maples typically have 3–5 lobes. Sweetgum seeds are contained in a spiky, round “gumball”; maple seeds are paired samaras (winged).

Germinating Maple Seeds

If the seeds are indeed maple (winged), sow fresh in fall or stratify 90 days in moist peat in the refrigerator, then sow in spring. Plant at a depth equal to seed length.
